The calculation for the volume of the cell suspension to use is: 1 × 106 cell/mL × (x mL/10 mL) × (0.1 mL) = 4 × 103 cells; x = 0.4 mL. Therefore, we need 0.4 mL of the 1 × 106 cells/mL that will be added to the 10 mL final volume of the cell-gel mixture.

How do you calculate cell suspension volume?
Methods. Use the following formula in order to calculate the number of cells you have in your suspension: (total cells counted)/(4 squares counted)*10-4*initial volume*dilution factor = total number of cells; Note: 10-4 is the volume of squares on the hemocytometer (0.1 mm3).
How cell suspension is produced?
A cell suspension or suspension culture is a type of cell culture in which single cells or small aggregates of cells are allowed to function and multiply in an agitated growth medium, thus forming a suspension. Suspension culture is one of the two classical types of cell culture, the other being adherent culture.
What is the ratio of cells to serum?
As a minimum in saline phases, 2 drops of serum to 1 drop of 5% red cells should be used to give a serum:cell ratio of 40:1 - ideally, the ratio should be 4 drops serum to 1 drop of 5% cells, i.e., a ratio of 80:1.

Why is normal saline used in red cell suspension?
solution on 5 percent red cell suspension However, normal saline solution (NSS) is more commonly used because it is inexpensive and easy to make. pH changes in the saline solutions and the RCSs were monitored for 1 week. Macroscopic examination of changes in degree of redness of RCS was also observed.
Why is normal saline solution used in red cell suspension?
Washing of red blood cells (RBCs) is carried out using 1 or 2 liters of sterile normal saline. This process is typically performed to remove plasma proteins and glycerol from the frozen RBC units.
What is a suspension of cells?
Cell Suspension is a type of bioink in which single cells or aggregates of cells multiply as they lie suspended in a predefined cell media. This bioink has been used in inkjet printers [54], and the cells can be used to aggregate without the need for a scaffold [55,56].

If the cell line is a hybridoma or another cell line that produces a substance (e.g. recombinant protein or growth factor) of interest retain the spent media for analysis.
Can cells grow in suspension?
In general terms, cell lines derived from blood (e.g. lymphocytes) grow in suspension cultures. Cells may grow as single cells or in clumps (e.g. EBV transformed lymphoblastic cell lines). For these types of cell lines subculture by dilution is relatively easy. However, for cell lines that grow in clumps it may be necessary to bring ...
